Study Notes

Types of Regression

Simple linear regression is used to identify the relationship between a continuous dependent variable and one independent variable.
Multiple linear regression is used to identify the relationship between a continuous dependent variable and one or more independent variables.

Linear Regression

The method used to calculate the line of best fit in linear regression is the Ordinary Least Squares (OLS) method.
The OLS method finds the best-fitting line that minimizes the sum of the squared errors.

Linear vs. Logistic Regression

Linear regression is used to predict a continuous outcome variable, whereas logistic regression is used to predict a binary outcome variable.
Linear regression assumes a linear relationship between the independent and dependent variables, whereas logistic regression assumes a non-linear relationship.
